Rear Idler Wheels and Axle
744-844A
DISASSEMBLING
1. With the skid frame removed, remove the cap screws
and flat washers securing the outer idler wheels.
Remove the idler wheels from the axle and account
for the adjuster bushings.
2. Slide the axle out of the rear axle housing and the
rear spacer.
CLEANING AND INSPECTING
1. Clean the bearings with a clean cloth.
2. Inspect all idler wheel bearings. Rotate each bearing
(by hand) and if any roughness or binding is noted,
replace the idler wheel assembly.
3. Inspect the outer rubber portion of the idler wheels
for cracks and poor bonding.
4. Inspect the plastic hub of each idler wheel for crack-
ing.
5. Inspect the axle for wear and damaged threads. Dam-
aged threads may be repaired with a 3/8 x 16 tap.
ASSEMBLING
1. In order, slide the axle through the rear axle housing;
then place a spacer on the axle. Slide the axle
through the opposite axle housing.
2. Place the adjuster bushings on the axle (on the out-
side of each axle housing). Make sure the adjuster
bushing is positioned properly toward the adjusting
cap screw.
3. Place the rear idler wheels on the axle and secure
with two cap screws (coated with blue Loctite #243)
and washers. Tighten to 20 ft-lb.
